FYI to anybody interested - a few weeks ago I ordered the Bolton 35A upgrade kit for my MiniST, with expected shipments to begin for this batch in January. Just got an email that mine has been shipped, with a USPS tracking number. I'm not too eager to work on this now in a freezing garage and was planning to install it after my Rad warranty expires in March anyway, but it'll be nice to have it in hand for planning the swap.
A nice pleasant surprise in a time of delays and shortages, so if you've ordered one or are thinking about it, looks like they're ahead of schedule; their webpage still says January, by the way.

For anybody interested in these 35A controller/display upgrade kits, FYI Bolton Area 13 has just sent me an email that they are on sale for US$199 ($30 off) and they have 1,000 units in stock. After paying full price and waiting a couple months for my as-yet-uninstalled kit, I'm just a tad envious.
