I'm sure I will take flack for this, but I bought my bow at BPS. Initially upon purchase, the gent made very minor adjustments and it was incredibly accurate for some time.
Then my son stepped on it or something (rest was waaaaay out), but it started shooting high and to the left. I took it back to BP and with laser etc he re-adjusted it for a grand total of $3. If I recall it was no more than $10 if it wasn't purchased there.
You might also consider picking up a book entitled:
Tuning Your Compound Bow by Larry Wise. @ $12.95 +/-
"Go as far as you can see; when you get there, you'll be able to see farther."
