You should seriously consider a Macdev drone dx. Runs of 100 psi and is pretty efficient. Its the best marker in its price-range by far. Easy maintainance too with few parts.
The best thing is, you can buy it new and still have money left.
If macroless is a requirement, i would go with a G6R.
Macdev Clone VX Brown/white
