Lube the rails, wax the string - regularly. The crossbow has much more friction contact than a compound bow, you need the lubes to help fight the high-speed wear on the strings and cables. I've shot several crossbows in the store that were dry, you could smell the nylon "burn" from the friction.
As far as a "good or bad" choice, we can't help you, you made a decision that was based on your needs, information, and how you hunt.
But, it would good to hear back when you have shot it for a while, and what the post-buy reactions are. I've had my eye on the local archery shop to look at one when they come in.
