I've been caging with cheap Chinese crap for the last year. I'm ready for a legit cage. Something better fit, better quality. At $100, what would you go after?
I like the plastic/resin style and I like to see my cock a little through the cage. Black is always preferred.
Koalaswim.com has a good selection of cages, most under $100. Some quite extreme, others quite tame. Most people seem to like the base rings that are a bit flatter and wide. Personally, I prefer metal, more of the mental aspects than actual security.
The Cobra mamba is by far the most comfortable resin cage I have found personally. Comes in black and holes for cleaning. eBay is usually about $20. I would suggest the HTv4 but cleaning is a chore as no holes other than just the one. I have a Cherry Keeper on order. Since I haven’t tried it I can’t recommend but it was about $70.
