CrissyK I know what you mean about if the bow might be "wussy" or not

but I have never really ever hear of any of the Excalibur models put into that class and they sell a 150lb model (about $400) but it is more a basic model with no camo colour on the bow (think it is a brown colour). The thing alot of people are finding out about the 225 lb bows is that they are too much bow for them. Remember that you have to put all the energy into the bow each time you shoot it. Even with the rope cocker, it can become too much work when practicing, makeing it not as much fun.
Another thing you should think about is where he will be hunting. Some States have a maxium poundage of 200lbs, so if he might get a chance to hunt in one of those States, you might want to limit the bow to the 200lb class.
About the investment part, I do not think you could go wrong with the Excalibur bows as they will hold their value. Just an example, try to purchase a used bow and they are not far off the price of a new bow.
By the way, I shoot an Excalibur Relayer, which was the first model they produced back in the mid 1980's and is in the 150lb class. Yes that is aprox 25 years old and I have not had anything major go wrong with it and is still as accurate today as when I got it.
Any more questions, feel free to ask.
