Everyone seems to be worried about breakage, not sharpness. A rule of thumb is that a steel bandsaw blade will be dull in 2-10 hours of use, and few people find it economical to sharpen them. Carbide tip blades last a lot longer, but require bigger wheels - I know one brand that will work on 16 inch wheels, but many brands require a minimum of 18-20 inch wheels. (I ordered two new carbide blades yesterday, 178 inches long)
One person I met was looking for a better bandsaw. He did not know how much use he had on his blade. I convinced him to buy a new blade, and the next time I saw him, he was no longer looking for a new bandsaw - he was happy with his, and a believer that 5 hours is a lot of cutting for a bandsaw blade.
On my small (14 inch) bandsaw, I normally use Timberwolf blades, although some people claim there are other brands that are cheaper and better. On my big (24 inch bandsaw) I use Lenox Woodmaster CT (Carbide Tip) blades.
