A lot of people recommend the Flying Pig dryer, but I bought this instead. It comes with more attachments and is rated at 4.3HP vs 4.0HP with the flying pig. Also, it's only $110 (was on sale for ~$85 on prime day).

I haven't had any problems with it so far for my own dog. Build quality seems good although you have to be careful with the clips because they can break and I've read it's hard to find a replacement clip.
