I've been planning on getting an Alpha 352 (need to sell some stuff first, and wait for the right deal..), but the Go 25 is being sold off really cheaply at the moment.. (€120 shipped, compared to €175 or so for the Alpha..) I'm not a super uptight racer, so the difference in runtime is irrelevant.. I do however love my Argus, and have the right pipe for the Alpha(0801) - but I have others that would surely work with the Go..
