I took a train to Monterey from San Diego to buy a VX and drive it home. This was after I had looked at a few that had been in accidents or that had been modified or abused. It took me about 4 months to find it. I only paid $2000. It had 220k miles before I swapped in a fresh japanese motor.
If someone is asking more than blue book just walk away. VXs are known to have problems especially with the super expensive and hard to find O2 sensor. That's the main reason people are selling them. Another reason this car has problems is because any small vacuum leak causes the engine to buck like crazy.
But as somebody mentioned, you could easily buy a DX and get a JDM D15B VTEC-E. I see them on ebay occassionally, or you can contact an engine importer. Try calling Attarco

I would advise against using a chipped ECU because you're not likely to ever be able to match the factory ecu calibration.
You can get the VX rear diffuser and front lip spoiler from Majestic Honda.
You can also try car-parts.com. I've had a lot of luck recently finding hard to find parts.
I would stay away from the CRX simply because it's OBD0 and has a cable transmission. But if you're willing to you could get a full OBD1 harness and bolt a VTEC-E onto your cable tranny.
One last thing. The HX motor is so much better than the VX. It gets the same mileage, but doesn't use a wideband O2, and it makes almost the same power as the EX/Si engine compared to the 90hp VX. The HX is OBD2 though and you might have some trouble finding the correct ECU.
