It's summer. Hot. A/C's running full tilt. If you DIY, a mid-range priced unit will rock your world. If you have more than a few cars/different types, you'll wonder what you were waiting for. haha
Everyone makes one, from nearly free to plus $100up. $60-$80 can fill the 'home garage' need nicely. Used right the system will be air free and filled in a few minutes, 0 mess, bottle-jockeying, purging or wondering. Expansion tanks, heater cores, tilted radiators(camero/firebird/vette/others), remote radiators, problem solved.
There are too many to recommend just one, but too cheap and the valves/gauge/inserts are not so good. You can even make your own.
