MTG Salvation

What are some of the better (and budget minded) sets? I'm just looking for generic power across all the colors and my collection isn't very big.

To clarify, do you mean play-sets (4-ofs) of generically powerful cards, or a set (e.g. Shadows Over Innistrad)?

Sorry, I meant the sets you can order of a certain rarity from the particular sets. (you get 1 of each card and people often buy 4x of a particular set if they first do buy them)

So, do you have a price range and any preferences i.e. do you like control magic effects or value cards like Thragtusk?

This probably sounds like a lazy cop-out but I personally think that Shadows Over Innistrad is by far and away your best bet. Just look at my set review if you want to get an idea of the number of playable Uncommon+ cards because it's a huge % of them relatively speaking. It's an insane set for multiplayer Mages.

Buying two copies of any Commander deck you think fun and then build 60 card decks from those cards is pretty good.
