I was picking up an order today at Home Depot (Lisbon, CT) and happened by a pile of Everbilt 1/2 HP Stainless steel sump pumps on sale for $52.03, down from $206. SKU 1000026682 model SP05002VD UPC 6948217021101. These are pretty heavy and the type that you park in a sump hole, not ones you'd move around.
I have photos but can't post from mobile.
EDIT - added photos from PC. Yes this is likely YMMV, there is another thread here from someone with 1/3 HP Everbilt pumps, but being store clearance, it is what it is. Fantastic deal if you are in the need and can get one. Again while these could be mobile they are really the type that are designed to sit in a sump and be permanently piped. you can see there were about 12 at this store, located near (but not with) the usual clearance stuff.
