I would get the universal fit over a caliber specific one for sure. That one looks good for the price, and those universal ones should fit the rimfires nicely as well.
My brother's birthday is coming up later this month and the last time I was at his house, he was in the process of changing scope configurations on three of his rifles. He mentioned that he'd love to have a laser boresighter, so I've been looking around the last couple of days to see what I can find. I can't really find a lot of information on them, so I'm hoping that I can get some advice here from those of you that own or have used a laser boresighter. He has quite a few different calibers, so I'm leaning toward the universal boresighters such as this one below that is offered by Bushnell rather than the "cartridge" style.

I got one from Walmart that worked for everything from 22 up. It has these screw in adapters to keep it centered. I don't remember the nae brand and I don't see anything stamped on it on it but it wasn't real expensive. I've had it over a year and it's been great.
[Edit]
I found the paperwork (it has a range finder guide on it) And it says it's a Laserlyte Made in Az. The site shows them pretty pricey but I think I got mine for 35 bucks at Walmart.
Here's the website

Their boresighters look pretty similar to the Bushnell I ordered. It hasn't arrived yet, but I'll be sure to post back once I get the offical review from my brother, lol.
BTW, did you look around on Laserlyte's site? They have a bayonet adapter for a pistol, LOL.
