I wouldn't pay more than about a hundred Euro for it, with ten pounds variation for condition. The model I saw, a 422g, was able to construct a complete condominium in about seven minutes, once provided with sufficient raw materials, and that was about AUD$150 two years ago. But of course it's the raw materials that cost the most and are the real problem - the only real injury risk is due to standing too close to the thing during operation; if you just push the 'on' button with a stick, say about two furlongs in length, then you should be well clear of any hazard.

I saw a guy at a computer swap meet selling a Pro Master XP Deluxe 2000 Plus, but it was wrapped up in one of those grey anti-static bags so I couldn't see what it was. Anybody got one, and is it compatible with Linux?

I've got one, and it isn't Linux-compatible. A simple reason - it's a sandwich (from TS Safebury's new gourmet 'Too good for the likes of you' range). The anti-static bag is intended to stop the finely chopped Patagonian onion tops from tainting the bread - which is rolled flat on the firm thighs of Cuban virgins. Seeing as the bread reeks of either tobacco (if the virgin in question is one of the three remaining female such to be found on the island, and therefore moonlighting from her job in the cigar factory) or sweat and pheromones (if it's the one, very lonely and self-obsessed male soul on the island who fits that description - he's the one hosting a rather-too-detailed website on the history and intricacies of the Havana underground, which hasn't been built yet) the task of stopping the finely chopped Patagonian onion tops from tainting it is a tad on the pointless side. The bag does, however, serve to ensure that the baby kangaroo which forms the main sanwich filling is actually dead (a known flaw with cardboard wrappings such as those used by Pret a Manger).

My neighbour has just had a small consignment of Farbulex granules delivered. Should I move?

d (it just fell out onto my desk)

It depends on whether they are the A-class or B-class. If they are the more dangerous A-Class Farbulex Granules, then I should seriously consider moving at least as far as South Africa. The US Government has long suspected that Sadaam Hussain had such weapons, and now it would appear that they have been found, and that your neighbour is in fact harbouring them. I would advise you to inform the police of your discovery immediately, for the good of all mankind.

If they are the less harmful B-Class Farbulex Granules, then your only worry is to make sure you rinse the sink out well after you have used them to clean your carpets.

One product that puzzles me slightly that I noticed the other day is the Ribo-Oxyaerator 250B of which I saw a demonstration not so long ago. Unfortunately, the wife was with me, and she saw a particularly wonderful pair of shoes at the same time, and alas, I was whisked away before I could see what it actually did. Has anyone seen one in operation?

This is a device for making Ribena wine. Just fill the device with Ribena, add yeast, and switch on the oxy-aerator. Be careful not to leave it going too long, or you get blackcurrant paint stripper instead.

My geek neighbour casually mentioned, in a manner clearly intended to impress, that he was looking forward to getting a Titan ZXQ-9950i with 802.11w, Blacktooth, and Terahax. What do I need to keep up?
