I also am a recent 'long time ex-Linn owner'. I dutifully did all the upgrades for 20 years and like you, the cost of the Keel upgrade gave me pause. A couple of options to consider:
1. If you like the sound of the Linn, take the time and effort to learn the set-up. Up to date Linns do not require the frequent adjustments of earlier incarnations. Also consider the Origin Live motor upgrade and a proper stand. Both make a difference.
2. If you are considering a change; the tables suggested here are worthy of a listen. I would add to the list the Galibier Serac turntable with Artisan arm and Dynavector 17D3 cartridge. This combination is sold at a package price and fits your stated budget.
Good luck.
