Hi Lugia,
Oh that's fantastic, thanks a lot for your reply and providing me a list of "homework" to check out! :-)
A few I considered already like the Instruo Tona and the Intellijel Rubicon II however all the oscillators from your list are all good pointers and it looks like that I have to do a lot of reading, testing, verifying and making the puzzle of oscillators even more difficult but also nice challenging, I like that so no worries there.
A few brands might be difficult to get directly from a dealer here in Europe but I will check them all, especially those I can get here in Europe.
Thanks a lot again and kind regards, Garfield.
