When I had 6 19inch racks of hardware, one box was an Obeheim Matrix 1000 analogue synth [ Oberheim Matrix 1000 | Vintage Synth Explorer ] . It was so called because it had 1000 patches. Rather like Scaler, it was challenge to find precisely what you wanted because you fell asleep at around number 389.
On this basis and although it was panned here, I actually coughed up something under 30USD for Niko’s MIDI Pack, and with the bonus packs that number over 2,000 midi files. I figured if there were 30 good ones to use as a basis, it might be worth it at a buck a pop. IMHO, there were 30 (and more) that were worthwhile.

Just my opinion, but I need all the help I can get

I also got some sets from DMS, but they are focussed on EDM / Trance / Ambient, and there are some very good sequences in the sets I chose. You can download samples to see what sort of stuff it is. Some sets mix stems and WAV samples or loops in, although I prefer the plain midi sets. I have a couple of the ‘epic chord’ sets, which are quite useful … good voicing.
