Here are a few choices if you're looking for some budget MXLs.
As long as you understand (And I'm sure you do) that you get what you pay for. Mind you, these are much better than the dynamic mics. which are the industry standard. The list price is always a bit of a joke.
Two things I would say. Look at the street price. If you are paying anywhere between $50 and $250 then the quality is not going to change much within that range. In other words, a $200 condenser is not likely to be any better than a $75 mic but the flavours will be different.
Read the reviews. Look for similar experiences within these reviews to get an idea of what to expect from each item.
Almost every condenser has it's use but very few within your budget will be your "Go to mic" for every situation.
