Best used Minolta/Helios/other lenses

So I'm looking at all of the used lenses on eBay. I don't know which are good and have those amazing color reproductions. I am buying for use on Sony A230/A55. I want to get the amazing colors that others have shown using old film lenses made my minolta. What lenses do you guys recommend? I have heard good things about the 50mm macro Minolta and the beercan, but which would you buy if you had to fill the gaps in my lenses : 18-55,55-200,28-200,90macro,50 1.8,70-300,a230,a55

Ones I have looked at
Helios 58/2
Helios 28/2.8
Minolta 70-210/4 (beercan)
Minolta 28/2
Minolta 100-200
Minolta 50/1.7 (How would this compare to my sony 50/1.8?)
Minolta 50/2.8 (macro)
