What is the best blow dryer and the best shears and clippers for a mid-ranged price?

i am a cosmetologist. i am being told so many different things. so anybody out there that knows their stuff, i am looking to get a blow dryer with a diffuser and concentrator attachment, a rather long nosel, more long lasting than the cheapy kind, and lightweight. what brand would you suggest? also, is there any type of shears you suggest as the best to get for long lasting? and clippers. i have andis now and they dont seem like the greatest. any suggestions? i hear oyster is good.
