The PSR-200 is GRE's basic analog desktop scanner, it doesn't have a lot of features. If you don't need trunking or digital i'm sure it will do just fine on conventional analog frequencies. I have the handheld version the PSR-100 and it works great. But don't expect a lot of bells and whistles, but it gets the job done. I have never had a 340CRS so I can't comment on that on.
