The only reason Psimet might be worth the wait is price (and maybe help with component selection). Building wheels takes some skill, but you don't have to be a master craftsman to do a good job. I got a quote a while ago that was about 15% below anyone else, but my followup email went without a response. If money were tight I would jump through the hoops and wait a few weeks, but it wasn't worth it to me. I get that he's doing this as a side business, and I don't hold it against him, but building wheels is not brain surgery. Any competent mechanic can do just as good a job and you don't have to fight to hand him your money.
