I have a similar Hot air rework station, it only has the hot air part, I use Hakko nozzles. It works VERY WELL, the only problem I have is that I am not doing SMD EVERYDAY, so the paste does go off (just takes a bit longer to push out the tube and needs a bit more liquid flux (but my paste is 3 years old
it is kept in the fridge in a bio hazard bag
If you use the buy it now option, I would carefully check the tips, they are more than likely Hakko copies, I prefer ORIGINAL Hakko tips, they work very well (I have used 5 tips in the 18 years I have had my Hakko iron (I used to do production line soldering for extra money when other jobs were light on the ground)
The BGA rework station looks nice lol
I have never tried to hand solder a BGA, if I have a project that needs a BGA I have used a local assembly place to do the BGA for me (if you can find a smaller place, they will just do it for a low CASH price (I pay ~au$10 per BGA, and they Xray to check it is in place (extra au$5 for a hard copy film (never asked for it as I do not need a bit of Xray film to say it is in place, there word is good enough
