10" Sub driver - what $$$ to shell out?

I was thinking JL (10W3V3), but it's a pain to get them in Europe, way too expensive.

I also can't find JBLs, so there goes another good option (GT1041D)...

Given I appreciate tight & controlled bass (say quality rather than quantity), what else should I be looking at?

I've found Polk DB1040 and MB QUART Reference RSH-252 to be in my budget, also HELIX P10W, Hertz ES 250D, Kicker CompVT CVT10, PIONEER TS-W260S4 and some more.

The box is sealed and small in size (I will measure and report later).

Please suggest an SQ oriented driver...
