Can not say for entry level at all. Mid level is a highly debated opinion when the parameters are simply based on Mid Level only, but for me I would have to say the CTX. High end, hands down is the GPZ with a 19; just the stock GPZ through proper training on crummy ground like you would get in Switzerland, Austria, Luxembourg and Italy pays for its self after 80 hours. Take it to some better ground in Croatia, Serbia, Romania and your doing much better, northern Africa and your not going to want to leave. LOL
Proper training is a must though, and it helps a great deal more if you have a vet GPZ operator with you on your first 20 or 30 hours.
