Daemon Tools is one of the best virtual disc emulators available today supporting the most disc image formats of any program in its class. It's also one of the few (if not only?) virtual disc emulator that will let you create, edit, and burn any image format it supports. Unfortunately, with great power comes a high price.
This is true no longer...at least temporarily with the Daemon Tools Spring Sale:
Daemon Tools Pro Advanced - was €54.90 - now €24.90
Daemon Tools Pro Standard - was €36.90 - now €16.90
Daemon Tools Lite - was €22.90 - now €10.90
(Note: Daemon Tools Lite is free for personal use. Purchase of a license required only for non-personal use.)
These are lifetime licenses. Prices are for one computer, but you can piggyback more PCs/instances onto your license for €8 each at the time of initial sale or later from your account. Seems reasonable to me.
IMHO, that puts even their flagship product almost square into no-brainer territory (approx US$33-34). For that price you could buy a commercial virtual disc mounting program (Virtual CD US$29.95) *or* a disc image editor/creator (PowerISO US$29.95), but even if you bought both you wouldn't have access to everything Daemon Tools Pro Advanced can do & neither support nearly as many disc image formats, either.
This is another one of those programs I said I'd buy if they ever adopted sane pricing. Given my usage patterns with disc images this was a deal I couldn't refuse.
Hope someone else finds this useful!
