I've been playing Mono Blue Tron in modern. It's a fun control deck. Unne goes into a bit more detail in his post about it's win cons.
Previously I had been playing a budget version of Affinity. But, I figured I'll never shell out $200 for a play set of Mox Opals or $150 for a play set of Glimmervoids so I gave up on my Affinity dreams.
Also, if you want to look into formats a good one is Pauper. It's mostly played on MTGonline and the decks consist of only cards printed at common. It's a VERY fun format and most decks are in the $50 range.
