Probably your best route.
I don't want to sound like I don't like H&R, I like their older gun (especailly their shotguns allot). I had their 45/70 that shoot 2" goups at 100 yards with stock sights. I have their older Topper in 30/30 that has never failed me. I have a shorten 357 Mag now that is not what it's cracked up to be and had a bad CS experiance with it. Its just that for what they are and the price they are being sold for now, they just aren't as cost effective. They are going for $330 new around here. But I was able to go to KY and find a few in the $275 range. So its cheaper to buy the complete rifle IMHO.
A 30/30 with a Handi Grip sounds like a great option. I got my stock off of eBay cheap, and it was new. Just got to watch for them. But I think Midway has just the stock too, so that would be cheaper too.
