1. For build quality, I.C.E are amongst the best. They seem to last forever, and hold their values really well. I have a 5 year old ICE Trice, and it seems pretty bulletproof. That said, I've just acquired a Catrike 700, which is faster, lighter, looks better and is just as well built.
2. Depends where you live. If you're 'dahhhhn sarth' you have Dtek/Bikefix/Catrike UK, if you're well oooop north Laidbackbikes.
3. Most 'bent manufacturers with a reasonable range offer good quality models. Some ahem Chinese attempts look a bit ropey. Check components specs, weight etc. This is where you need to spend a few hours on t'web looking at reviews/forums etc.
4. New 'bents are ludicrously expensive. Best bet is to look on Forums such as this one/CTC/BrithishHumanPowerFiorum etc. They have classified sections, and most owners seem to take really good care of their machines. Don't be tempted to just bid on
ebay on a machine that you've never heard of, there are some really poor machines on there sometimes. I'd say you need to be looking at around the grand mark for a decent modern 'bent.
Depending on where you live, your best bet is to try and have a look at a few machines. I'd be happy for someone interested to have a look/a ride on one of my trikes (I'm in Doncaster.)
BTW, I've had a couple of 2 wheelers (Bacchetta Strada/Optima Baron) but imho trikes make more sense. They're more fun, almost as fast, and far easier to ride!
Good luck!
