a lot of question marks on that list...kind of depends what you think will be available on draft day in your league as well. first off, i would certainly not keep santana at that price...there will be plenty of guys available who are as good next year for way less. chacin could be a good bet-hes looked strong this year, and next year i would be surprised to not see him as a pretty solid starter (would be lovely if he got traded to petco or something, but little chance of that). the big question is really whether you want to sink a lot of money into howard, reyes, zimmerman...those prices aren't unreasonable, but its hard to evaluate without knowing what comparable players are getting, because if you know that your leaguemates are going to be dropping some big SS/1B names then you can maybe do without keeping your guys. I will say that I like reyes and zimmerman both a lot for next year, and howard will be pretty much what you expect.
given that you say you prefer to keep cheaper players, id say lose howard but keep zimmerman--they have comparable numbers this year, but 1B is deeper in my opinion and that leaves you with some extra cash as well. reyes is going to be solid, so of your other high priced options id say him--if you dont want to keep more than one of those bigger guys, tabata has a lot of potential for $5, pagan at $1 is a steal for the multi-category help he gives you...like i said, depends who else you think is going to be out there for next year. overall, you have a lot of strong hitting options depending on how much you want to spend, id try and focus on those and then look for some solid SP early in the draft.
