Well, ya gotta start somewhere, and with limited funds, get what you can and see what you can do.
Last year I bought an old craftsman bandsaw at a yard sale for $75. Turned out to be really old, as in no replacement parts were available. It was a 1/3 Hp and did so-so cutting small pieces of wood.
So later in the year, I sold it for $50 at one of our yard sales and consoled myself with a $25 lesson. So if you do go the used route, see if replacement parts are still available.
Fast forward to now - I did some construction /remodeling/ house flipping work for a couple of friends and used the money I made to buy a new bandsaw. And am pleased with it. There is an saying on the forum I've seen and subscribe to: "Buy once . . . cry once".
So, in my opinion, if you're hot to get a bandsaw, then go for it and see where it takes you. Regardless of how it plays out, you will learn a lot.
Good luck with it.
Oh, and a good blade does make a lot of difference in cutting and the quality of the cut.
