Acoustic measurements

Hi, I'm looking for a professional audio spectrum analyzer even capable of the other main acoustic measurements, if this is possible without any compromise. There are a lot of dedicated softwares (e.g. ETF with MIC/PREAMP) that cost less respect to the hardware equipments but I haven't any direct experience about the different performance. I would like hardware equipments because of practicality (software installation, calibrating procedures etc...) but if this is the better way, I will give up to hardware equipment. My budget is $700. Thanks, (sorry for my english) Salvatore.
