I really love TMR for buying things. I don't expect to get top dollar and realize that they're taking a lot of the hassle away for me. Ultimately, everyone has to decide what's worth *their* time or money, so I'm really just probing different opinions.
Markets are funny things. When there's a lot of data out there -- say, selling a brand like McIntosh or Klipsch, things are easy to price. Then, it comes down to whether one is good with their "cut." When there's not a lot of data out there, then it can get hard to price things, and so whether the "cut" winds up seeming reasonable is a more speculative affair.
