I have ZD-915
it's the cheapest desoldering station I could get locally (~70$) and it works like a charm .. whatever you get it will 99.9% work and if it dies you can cheaply fix it as it's psu that is the weak link. With zd-915 I got 4 different nozzles and 3 rods for cleaning it up + some filters .. I had a chance to use ERSA, DENON, PACE desoldering guns and while they look "nicer" they don't really work any better then this el-cheapo PRC device
As for the HEAT GUN, I use some QUICK knockoff of the hakko, I tried many hakko copies and they all work like a charm.
I personally prefer the HEAT GUN with the compressor and not the one with the fan embedded in the handle. I tried using them and for me that just does not work .. I can't say if it's the flow of air or the big handle or .. donno, I just dislike them, I feel weird using them (I have to admit having only a small cord is nice compared to fat cord my quick has)
