monitor solutions for thin wallets?

i'm on a bit of a budget and I need to pick up a firewire audio solution and some monitors for under $550 or so. im debating between M-audio monitors. BX5a vs. LX4. Which set would provide me with the most accurate sound? Mind you my studio is quite small at about 42 square feet in total size, so I doubt that I need a set that's super loud.

are there better monitors than those in the same price range?

id advise one waiting and saving for a little longer.

ive bought cheap equipment in the past, and you always regret it a year later

Ive got Yamaha MSP5A moniters for under 300 quid I like em nice and clear for the price man a bit harsh if you push em tho.
