XA is pretty inexpensive and plentiful. So is the GTN. Get them both? GTN - definately not pocketable.
Don't own the XA but I do own the Konica Auto S3 and a Yashica Electro CC. Of these two I prefer the 38mm F1.8 Konica. It's smaller, and the shutter speed goes up to 1/650. That said, the f1.8/35mm CC is no slouch either, also a fine camera but the shutter is limited to 1/250 and the camera limits you to 400 speed film (Konica 800).
Thinking of selling the CC. ($65, plus ship. Fully functional, VG condition. PM me if interested).
