choate makes some good stuff as well. aluminum bedded and some have pistol grips.
i had a green one designed by john plaster that i put on a remington 700 LA .308 rifle i built. it was about $200 shipped to my door. great stock. too clumsy to carry hunting but great for target shooting. it really helped cut down on recoil
the stock your looking at on ebay is a factory stock from an SPS Varmint rifle. the day i ordered my SPS Varmint i ordered a B&C A2 stock the same day. i was originally looking for the B&C M40 model. i knew the first thing to do was replace the stock. i did this before even getting glass. if you don't have the funds to get a B&C stock which will run around $200 i say you start sanding the inner channel of the Hogue stock till you can free float the barrel some. shoot it til you can afford a decent stock. i wish i would have waited and saved more money and got a higher end stock but am still very happy with the B&C. thats what i would do. good luck.
i dremeled my barrel channel out so it didnt touch. if you are finding too much flex you can bed an arrow shaft in there to stiffen things up. i find the houge stock very comfortable just a little flimsy
