Ian,
Jesel has a Sportsman Series that retail for $695 almost anywhere. I just picked up a previously owned, but new set for $500, but I have been watching for them very intently for the last 5-6 months. If you haven't already, read the post I made to end out my thread
here.
As luck would have it, I was also looking at a set like the ones you describe. The sellar says they have every option Jesel has, plus the setup tools and instructions. If you don't mind a used set for around $700-$800 check out this
NMRA post. This guy has been asking $900 for them but it sounds like he is getting a little desperate; I suspect he needs money quickly. I wouldn't offer him over $750 to start with. They may be used, but they should still be way better than stud or pedestal mount rockers.

PS On Rev's comments. He is absoltely right about NASCAR changing them frequently, BUT they run 1.9 to well over 2.0 ratio rockers also and don't take ANY chances. You wouldn't want that high a ratio and they are available in more reasonable 1.5-1.7 ratios. With the kinds of springs you will run on the street, they will last longer than anything else out there except T&Ds maybe. But there are cheaper alternatives that are good enough for what we would typically put on the valve train, unless you are going to race Le Petite LeMans or GrandAm with your '40. As to pre-oiling, you can bet your butt that I am putting an Accusump on my car: the cheapest insurance for your motor there is. If money is an issue, don't buy a new one. Buy a used one for 1/10th the price and put a $8 O-ring kit in it. If you want a switch control, don't buy Tilton's or Moroso's; you can get a 12V solenoid valve for 1/3 what they want for them that is as good or better. Either way, if you are putting the kind of money in your engine that considering Jesel Mowhawks or Pro-Series rockers would indicate, it is a no brainer on the Accusump. If you don't do Jesel,T&D, Crower or the other $1K and up rockers, I would stay away from CAT and Probe for sure. Other than these, they are all pretty much the same price: ~$700 retail. So Jesel and Yella Terra are the best two IMHO with a bunch in the middle and Harland Sharp at the low end.
