hi there, iv'e had both models 1n 177/22 for hunting and formal paper punching. IMO, there's no comparison to the 100. solid construction and user serviceable. ive one of the first 100's still, the only major thing its had is a trigger spring and cylinder swap and the latter was only to make the gun lighter, its been out all weathers and bar knocks and dings to the wood and wearing of the bluing its needed a few orings due to leaks etc. unless hw revert back to mainly an all metal/alloy pcp or a well proven modern material one that beats the 100 hands down ill not bother im afraid. major birthdays come but once and honest monies are usually hard earned, if it was me in your situation id be spoiling myself else where.. atb gc93
