I know you know, but there are many of us that don't understand the attitude of "I refuse to buy decent tools," especially when it comes to things like bandsaws. I use my bandsaws (yes, plural) more than any other tool by far. IMO, the old adage that "it's a poor carpenter that blames his tools" is BS. If you have a crappy tool that won't stay in tune (if it even gets there in the first place), of course quality will suffer. Not to mention the time and frustration it will cause you. To me, that has a cost too. My advice is to listen to the advice of those that are more experienced. There's a reason why you get comments like Spokes: we've been through it all before, and we're trying to pass our lessons learned on to you to save you money, time, and frustration. But there are of course those that plug their ears and dig in their heels who just need to learn things for themselves.
With that said, a good quality blade on that saw sure can't hurt. Also, check out the "Mastering Your Bandsaw" DVD from Fine Woodworking/Taunton. It shows you some good techniques for tuning and sawing.
