Don't forget the clarinet forum at www.woodwind.org It's excellent for getting help and advice.
I post there occasionally (prize for the first person to work out who I am!). The regulars who post there know an awful lot, but there can be an overwhelming smell of anorak occasionally!
Randall - go for it! You might have guessed that we're all a bit biased around here, but it's just such a super instrument <goes misty-eyed thinking about clarinets>. As everyone else has said, the transposing instrument status only becomes an issue when playing with other people.
The only time I wouldn't recommend clarinet is if you want to play loads of pre-Baroque music, because there isn't any (except arrangements).
People have suggested a few brands and models, all of which seem good choices. The big brands are Buffet, Selmer (the American wing is either Bundy or Selmer Bundy) and Yamaha, and I've heard good things about Hanson (not just from stevensfo). I've always been keen on Boosey and Hawkes clarinets, but they're no longer in production.
You will need an ordinary Bb clarinet to start with, and can move on to bass or Eb later. Most student models are plastic, and whilst there's nothing to stop you learning from scratch on a wooden instrument, you might want to get the hang of your blowy thing before spending £1000 or more on a really good instrument.
A few people have suggested e-bay. Whilst you can pick up a real bargain, there are a few turkeys there too. Make sure what you're buying is a Boehm system instrument (which it probably will be, unless stated otherwise. Boehm system instruments have the right number of keys. There are a few, really rough-looking Albert system instruments manufactured overseas and sold cheaply on e-bay, so beware of these). The general rule of thumb is that if something seems too good to be true, it probably is! elidatrading, who sometimes posts here, has useful advice on purchasing through e-bay on her website.
Let us know how you do, and welcome to the world of clarinets!
