Hi
Having something that cuts off square is very useful, especially if you scrounge off cuts like, we do. We had a band at work and it was quite rubbish. Wasn't cheap and couldn't cut Ali square. We have great big one now which is really good but very expensive. I like the old reciprocating types, they are rare now. I got one free. It was being skipped because of a broken gear. I grabbed it (quite legally and with consent), it's a sealy last listed at £1000 or so, well beyond my means, rang Sealy and £12.50 got me a replacement gear. So my advice, keep your eyes open wide!
Work threw out a lovely pre war band saw while I was on holiday, because it didn't have interlocks on the door! Eyes open wide. I guess you're not local to me but for a very small contribution (to pay for blades), you can use mine for free. Capacity is 20cm x 20cm.

I wouldn't buy the 45 degree bad type again.
