Got my canner recently and did first run of meat canning yesterday, and It was a success! I went with pork jowls, as it is one of my favourites anyway; fatty, juicy and it's most affordable (around 3€/kg), it's quite similar in taste to pork belly, actually.
I raw packed the jars almost to the brim, and added some chopped garlic, rosemary, salt, pepper. I'm using standard "Euro" 750ml jars and lids, those described by Psyche way back. Processed them at 10psi for 80 mins, and all were sealed when I checked in the morning. Little fat did spill out, but the contents look fine to me, I havent tried any, as there's still some roast in the fridge to be finished :)
As for equipment, I found a cheaper alternative to Presto, it's a Mirro brand canner, and apparently the company has been producing them for quite a few decades. While weighing in pros and cons, this one won for me for several reasons; it's a weighted canner by default - no need for extra pressure regulator valve ("jiggler"), you get 3 weights (5,10,15 psi), white silicone rubber seal - some folks claim that's superior to black rubber seals, and it comes with 2 canning racks in 22qt version, not sure if that is the case with Presto 23qt? And all that at 30% lower price. (Got mine shipped to EU via ebay for 104€, import&tax incl. vs. 154€ for Presto with pressure regulator from Amazon.)
The cons are; no pressure dial gauge, I know, those ARE cool
, not recommended for glass tops/ceramics (although there are reports of people using them on those with no issues). Most critique of the product is concentrated on somewhat lacky manual, which is true, but there is info on the net. (Jiggler weight has to be pressed fully down to properly seat, and jiggling 3-4 times a minute means 0,5psi above pressure, which they failed to mention). All in all I think it's a very straightforward and quality product worth considering, for those who still haven't bought one and plan to embark onto canning, fwiw.
Here are links to 22qt version on ebay, manufacturer's site.

P.S. I'm in no way affiliated with either seller nor manufacturer, just pointing to alternative product for those willing to spare themselves few tens of euros. ;D
