It's really hard to find one like that. Really.
I like its length/girth as well. If you're okay with bigger girth, Randy has a similar length I do believe. Otherwise, you might want to check out a Tantus Silk Large (similar in size, I think?) or other FunFactory toys as the Amor is one of their "short dildos". They do have other "short dildos" like it, but I'm not sure they're still in production.
