Like I said in the other post, most folks purchasing the LX didn't pay for the ABS, else if they did it made more sense just to buy an EX model.
If you are looking used, why are you not also looking at the '00 Special Edition and the EX models?
A buddy of mine in NE Ohio in the past was also looking for an LX w. ABS, I'm sure it is by no means a rare car, Accords are a dime a dozen. But the non-ABS LX is just so much easier to find.
If ABS is your big ticket need, open up your search to '01-'02 Models and the EX line of cars. In the used market the price can not be that huge a difference since used prices tend to eb and flow based on sellers preferences and mileage.
