Another vote for the 20-39PC+... although if I were buying now I would also look real hard at the EP500. In Canada they end up costing about the same once you include shipping... not sure how the numbers work out in the US.

M60ti, VP180, QS8, M2ti, EP500, PC-Plus 20-39
M5HP, M40ti, Sierra-1
LFR1100 active, ADA1500-4 and -8
