Best service manual?

For a 94 LeSabre, what's the best service manual currently sold at stores? One with good graphics and photos. Is there any way to get the specific LeSabre 94 service manual instead of the ones at stores that are for a bunch of similar cars? I mean, within reasonable price, of course. GM probably sells it at $100, but I'm thinking $20 at the most.

Thanks

Try eBay. I always see Factory Service Manuals on the site. I've purchased many FSMs for my vehicles on eBay and the most I think I've paid is around $25(without shipping). Not bad when you consider they usually go for over $100.If you don't see one in your price range or one at all , keep checking back on occasion.
