Go with an 08 ego. The diaphrams takes about 10 mins to replace and only needs to be done about once a year. Other than that they are easy to maintain and shoot great. I run a youth team and had five PMR's but so much problems with pmr's that we switched to ego 08's and we have not had any major problems since. The other great thing about ego's is they are pretty common around here so there is always someone around that can help if you have any problems.
