To me.. Is it worth saving the money using a set of used lifters, no matter how many runs, versus having to replace the cam and the lifter if they fail.
Remember you break in an engine by seating the rings to the bore, the bearings to the crank, and the lifters to the cam. That means they wear into each other, so old lifters wearing in to a new cam just means additional wear.
I've seen new lifters fail during break in several times.
My opinion, yours may vary.

Take out your lifters, put a straight edge across them, if there is any crown their usable, polish the foot with 600 wet/dry paper, do not sand only remove the glaze (shine), if any lifter is flat it needs to be refaced (most cam grinders can do it) around here cost is about $3.00 per lifter, however I don't like to do it, I think it removes the hardness, yes you can change the cam and lifters on the stand, there is plenty of room, you do not need to take out the crank. 

It took me 25 years to find that tool, it's not for sale, Ford sold them and almost all dealers had them, also KR Wilson and Manzel sold them.

Check out Manzel tools on E Bay

Checked out Ebay for any Manzel tool that resembles the one you have, but nothing there. The other thing that concerns me about using my lifters with a new Isky cam goes back to Ted's information regarding the lifter bore angle. If my lifters are broken in on a Comp Cam which was ground based upon a 41 degree lifter bore angle and I install the Isky Cam which is ground on a 43 degree lifter bore angle, my lifters will not be making contact in the same position on the new Isky cam. Does this really not matter or is this a real concern?

All you care about is the crown on the lifter, if it's there means little or no wear, If your worried, get new lifters, the best ones are made by Trend, they never wear  and can go from cam to cam
 (tool steel) 

Trend tool steel lifters, I think is what Cliff means.

If you want that tool, keep scouring eBay.  One is bound to show up.  But you need to be willing to pay whatever is being asked.  It's one of those things that you need to buy when available.  No going to the guy across town for a better price.  Probably not a solution for the time frame of the next several months.

Here are pictures of a couple of different lifter tools for the Y.  The original boxes eventually fell apart and I’ve put these in some custom wooden cases to keep all the parts together.  You can see the troughs that are used to capture the lifters.  It’s wood on one of the units and metal on the other.  Both lifter tools swivel the lifter 90° when working the triggers.

Personally taking the chance of used lifters failing on a new cam is not worth the price of a new set of lifters. When I was young and broke I would have chanced it. Not today.
