none of that stuff is very good and 7" or 8" is not enough room imo for anyone. most of the pump co's recommend 2"-3" of empty space.
none of it can be upgraded or is modular. i like these Leluv cylinders in 9" or 12" if you're huge. these types of setups can be upgraded to larger or smaller cylinders or if one part breaks the whole thing isn't shit.
electric with everything. pump can be used with many other cylinders & cups

or this type, there's no one and done package for the mityvac type hand pump i like but here is all the stuff you'd need. the mityvac style hand pump is imo the best, it's easy to use one handed, you can pump up and hit the pressure release easily with your index finger. gonna be much easy to use than an electric.
