You can still get real MEK (the Weld-On products like 2354, or the old standby #3 and #4...now labeled SciGrip) online and shipped with no crazy-expensive hazmat shipping if you shop around, and you may be able to buy it from a local shop that fabricates plastic signs or displays.
EDIT: A pint of the stuff runs about $30 shipped to your door now, higher that it was in the old hardware-store days, but still way cheaper than buying little bottles at the "hobby shop".
