My father and I have been avid hunters since I was 14 [i'm 26 now], and 2 years ago he had to move to Turkey [great place btw!] for business. Hunting there is pretty fun, lots of small game, boars/wild pigs, deers and such - it is however real hard for a foreigner to get a legal rifle, and we won't go down the illegal path of course. I have discovered that i can send crossbows over w/just paying the custom's tax, and wanted to introduce my father to xbow hunting as a birthday gift. I'll be leaving the US in about 6 months, and live with him, and hopefully start hunting once again.
I know he had dabbled in bow hunting before - although not for a long time - and I have never in fact. My quest is this: buy two nice crossbows [max 150$ per xbow maybe], buy whatever parts that will need replacing over the course of a couple of years: last time I was over there, I have not seen a demand for xbows and consequently their parts, and few, very few hooby shops carry few xbows and parts [if at all]. I have no idea about xbows right now, and I unfortunately do not know anyone around me to give me hand on them. I want to make the correct choice of a xbow the first time, and I'll need your help for it

I did a search on ebay, saw 180 lbs. xbows for fair prices, would those be a good place to start, or just like in archery, i need to get something according to my/our body size?
[long question i know, but i need guidance
