There is no doubt that OS's are good engines. however, with the appearance of computer controlled manufacturing techniques, many other brands give you more for your money. Many of the lesser known brands are now nearly (if not as good) as good as OS. Enya is certainly one of the top brands brands but, if you are a beginner or strapped for cash, check out the TT, Magnum, etc. Enya has a good reputation for long life, much better than most others.
