also, in response to PSIMET's long lead time w/ emails, I think he's gotten much better at responding. My communications w/ him were frequent and fairly quick. I think the most important thing is to inform him right off the bat that you're seriously interested in purchasing a wheelset and that you're ready to PayPal him as soon as you agree on a configuration. He gets so many bs emails every day that I can imagine how difficult it must be to weed out the silly non-serious questions with the serious buyers.
I think it only took 5-6 emails each to get to the final invoice and to send him my payment (2-3 days tops from my original email).
So don't let other ppl sway you away from him because of email response. If you decide to go with him just include "money in hand", "ready to buy today", etc in the email subject or in the very first sentence so as to grab his attention. It worked splendidly for me. Just do your research and know roughly what you're looking for or at least your price range and what you're looking for in your wheelset.
I was deciding between PSIMET and Boyd back in January and I sent PSIMET an email inquiring about wheels. He never responded, so that made my decision quite easy. I ended up contacting Boyd and we went back and forth with emails over the course of a few hours, because he was responding quickly. I ended up getting my Boyd wheels built with Alchemy hubs, and they're fantastic.
I find it silly that I would need to advertise that I'm ready to buy with "money in hand" just to get a response. What happens when you need after sales service? Do I need to flash a few bills to get an answer?
