Basis 1400 TT...

Audiomods arms are fantastic and in your budget.  These are completely reworked Rega arms, so straight drop in on your table.

Excellent reviews.  I have (2) of them and they are indeed terrific!

if you decide you want the micrometer (invaluable for fine adjustment of VTA/SRA), it also is not offered on the Classic

That's not true.  It's a 90 Pound option and includes the VTA lock.

I would just opt for the Series 5, (which I did).  It's worth the extra money.  I also have a series 3 or 4, I can't remember which.

Even if you can't afford the series 5, the Classic is a hell of an arm.
