None of us can tell you anything except for what we would do and we are all different. It makes for a wonderfully varied thread though:yes:
Personally I always have to have 2 systems worth of stuff working (all in the same system:scratch2

. I would take a long time and peruse CL, Barter Town and keep an ear to the ground too. I would buy one item at a time integrating it into the current system and evaluating it as I go. Always replace the weak point if possible but if an upgrade comes along that is a great deal go for it. After evaluation put the unneeded gear on Barter Town. You will constantly have something new going on. There will be constant improvement. Mistakes will be minor and possibly sell for more than you paid. You only need enough extra money for one item at a time. You will be entertained for years! When you are finished you will be certain that this is the best you ever had. BTW You will never be finished, the bug is not curable.
