The HP100 is closest in size as already stated, but personally I much prefer the Faber over the Worthy tanks. Faber are less negative in the water, a little taller (I am 6' tall so short tanks dont work well for me), and they don't have as much roll in the water. Another great choice is the LP85. Many people will over-fill them and get a pretty substantial volume. They are even less negative than the HP100 and maybe a bit less expensive.
I own four Faber HP100 tanks, all Faber...two singles and one set of doubles. My singles I left the yoke plug in as my reg I use for single tanks is still yoke. I've found that yoke is what most tanks are where I've traveled. I have the DIN kit for it should I ever change my mind or need it.
