I've asked the wife if I can buy a Paramount MX+; the laughter that ensued meant "no", I'm assuming.

You just really need to make a little checklist for possible errors:
1. Polar Alignment OK?
2. Scope balanced in both axes?
3. No cable drag or obstacle?
4. Autoguiding on a single star not a double?
5. Guide rates correct? (.5 sidereal is common).
6. Guide exposure length about right? (1-4 seconds is usual as much as 6 on a high end mount, shorter on a not so good mount like 1 second).
7. Are you getting flexure? Adapters all tight, when you press on the imaging train does it flex?
8. Guide scope flexure?
9. Something loose?
10. Autoguider not calibrated?
11. Getting hot pixels that the software confuses with the guide star? (sudden large errors like 13.5 are hot pixels) Use auto dark subtract.
12. Something wrong with your mount? Gears meshing too tight or too loose, some play , something stiff and tight needs loosening or regrease.
13. Tripod/pier not stable. Mount not levelled and way out?
