Prudent. The lack of feedback is a legitimate concern. Take your time, watch Ebay for a while and get familiar with it. Also watch our Seen on Ebay section and watch the reactions of our members to various listings. Get to know the things we look for in a listing. And take your time getting to know Alembic and Alembics as well. Spend as much time as you can reading the threads here, learning about the models, the electronics, etc. And have fun; there's a lot of really cool people here and lots of really cool stuff to learn about.
