I've transitioned to mostly shooting Vertical bow now, but used crossbows for years before as well as my dad, due to a shoulder injury. We've only ever used Tenpoint and I can say it's been similar to Leupold, the best warranty you'll never have to use. I've got no incentive to look at another brand. I have also heard that the Excalibur, Scorpyd and Mission xbows are also great. I know lots of folks love their Raven's but I wouldn't spend my money on one after all the honor stories of broken limbs/ pockets a few years back.
It sounds like you found a great deal on that one, if you like how it feels and shoots then I say go for it, I don't think you'll be disappointed.
