ISO advice on record cleaning fluids

I'm looking to compare notes with vinyl fans who, like me, haven't sprung the big bucks for an ultrasonic cleaner (such as the one made by Audiodesk) and who still use fluids to clean their LPs. I clean mine with a VPI HW-16.5 vacuum machine, but for really dirty records (e.g., garage sale finds) I add the extra step of washing them first in a humble (but for the price, very effective) Spinclean. With the VPI machine, I've alternately been using Mobile Fidelity solutions, as well as those from VPI. I am, however, curious about other solutions -- especially, based on the reviews I've read, those made by Audio Intelligent (AI). So I'd welcome feedback for any of you who have tried other solutions. Thanks
