My Harvest Maid round, stacking dehydrator finally died in December after doing 30 years good work. I would recommend it in a minute, and buy a new one as well, but they don't seem to have the same type or quality anymore. I could be wrong, and perhaps didn't look hard enough, but I haven't heard many good things about the modern ones - I think the company is Nesco now. Anyway, I did spring for the 9 tray Excaliber as a replacement, and must say that I like it very much. It dries things more quickly, but it is louder than the old one. I don't run the machine overnight because of the noise - but the bedrooms are just down the hall from the kitchen, and the kitchen doesn't have a door. Be aware that that 10 year warranty is only (or was only) when buying directly from the company. I got mine through Amazon, and I think the warranty is only 5 years.
As to canners, yes, many people swear by the All American, and I am sure that it is a great product. However I have a glass top stove, for which the AA is unsuited, so I got the larger Presto, and it is a perfectly good canner, and quite a bit cheaper. It fits 9 quarts or 18 pints. If you buy this one go the extra step and get the 3 part weighted jiggler, which is extra. The pot comes with a weight, but it is a single weight of 15#; the 3 part one can be taken apart to make 5, 10, or 15 # weights, and saves you having to watch the gauge all the time.
If I had your budget restraints I would opt for the Excaliber (which might be a bit more than your budget allows) and the Presto (which is less), and thus have everything even out.
