I think I would rather havebabscarlet, the l600 it also pretty sweet looking and I can't find a l273. $250 would probably be around the max. I've been trying to convince my wife that a $500 kk flowerhorn is a good idea.... Still hasn't happened...Ridiculous is pretty expensive. I spend like 250 on my L095 which most people would think is ridiculous, but I found it reasonable. hahah
Breeding of most rarer plecos, especially the larger ones, is difficult at best. I have not personally seen anyone who breeds L024. I have seen a guy who has done 600s. L273 are great looking and pretty much have the same care as the 24/25/600s. They are not cheap though
There is also the typhoon pleco if you like the cactus type $$$$$$$
