I've often said that the $150 I spent on my HF band saw was the best $150 I've ever spent on tools. The saw itself is good, though it can be a bit frustrating to get it trimmed out just right so the blade doesn't pop off the wheels. That'll give you a little instantaneous pucker the first time it happens! But rest assured, the saw can be trimmed to run well.
The most important thing to know is buy good bimetal blades for it, and keep a spare blade. Someone here will tell you the best number of teeth, I can't remember what mine are.
As to how fast you can cut 1/4" A2. Well, let's just say that I've sworn off 1/4" O1 unless I really have to for some seriously profitable reason. I'd had a couple years off until lately; for my first project I cut a large blade out of 3/16", and my arms were freakin tired! (I'm an old desk jockey though, and it's been winter for too long.)
But if I'd have had to drill around the profile and saw the dots and then grind them off - I'd either still be doing it or I'd still be not making.
Get the saw. You'll be really freakin glad you did.
