32 bit Clean roms for SE/30 and Tantalum capacitors.

Ok, so for 32bit clean replacements there's...
ROMinator II
BMOW
GGLABS MacSIMM
Garrett's GW4402B

What others are there?
 
If you don’t care about the in Rom disk images, or disabling the memory check, is there any other advantage to replacing the ROM over mode 32?

The IIsi-based ROM is less picky about which RAM is in which slots. It will work with RAM only in bank B for example.
 
The one annoying thing with MODE32 is on boot... it shows the happy mac screen, then gives a blank screen, then follows with the normal Welcome to Macintosh screen. I think this is where it's doing it's patching?
 
Yes, MODE32 does a separate memory test after flipping into 32 bit mode. It does also call the Close method on the video driver which canonically should disable the display (but SE/30 CRT can't disable video, so it just stays as is).

Technically, my ISP-SIMM is also 32 bit clean when an IIsi ROM is flashed, but that's more in the nature of a specialized development device :)
 
Rominator II looks a good option except for the altered logo and the slot fit issue.
The Rominator II doesn't come with the fitment clips, because BMOW was able to find a PCB manfacturer who could make the proper 0.5 mil size:


and previously mentioned


This phenomenal video from JDW mentions that both the Rominator II and the GGLABS' units are same thickness as the original stock ROM:

This link goes right to point in the video where this is discussed:


I'm interested in the Garrett’s Workshop GW4402B because it has multiple ROMs from the factory, selectable by jumpers on the ROM. Thats pretty cool!! I'm trying to verify if it has custom logo and boot chime, which is something I'd prefer not to have.
 
The Garrett's Workshop facebook post announcing the GW4402B also mentions they've been able to beef up the thickness of it - it sounds like it has some great features. I didn't know it had multiple ROMs selectable via dip switches on the device. It also has a control panel to configure some aspects of the device like if the ROM is mounted as a disk on boot, using it as a RAM drive, etc:
