Blindscan recievers.
1/ Manhattan Plaza XT series
2/ Vantage X200S series. Blind scan in 1,2,3,4 or 5 MHz scanning steps. Tunner about as sensitive as TM1500CI+Super, but not quite as sensitive as TM5200usb or Plaza XT-F.
3/ Technomate TM1000 Super series
4/ Technomate TM5000usb series
5/ Manhattan ST series
6/ Echolink EL777
7/ FortecStar Lifetime Ultra

Own Vantage X200S, Manhattan XT-F, and TM1000 blind scanning receivers. Find the Vantage X200S best and fastest for blindscans.
I dovercat own a Manhattan Plaza-XT.
The Manhattan Plaza-XT blindscan in 1000-2000 symbolrates 4MHz steps, 2000-4000 symbolrates 4MHz steps, or all symbolrates 8 MHz steps. You can also stipulate the starting and end frequencies for the blindscan and the polarity to be scanned. It is relatively fast, especially all symbolrates 8MHz steps scan but it occasionally misses a low symbolrate transponder that a slower 4MHz step scan picks up.
The Manhattan might in theory miss a very low symbolrate transponder if it is was very close <4MHz away for a very high symbolrate transponder, that a Vantage X200S should find due to its smaller as low as 1MHz scanning steps. But the Manhattan allegedly has a faster blindscan and slightly more sensitive tunner so it might find slightly weaker transponders than the Vantage can. So its swings and roundabouts.
The receivers above are only DVB-S so you might want to look at getting a computer satellite tuner card or different receiver as the number of feeds using DVB-S2 is apparantly increasing.
