Few questions about DB Electrical starter..

[dustnx]

I just had a couple of questions I was hoping some could lend some insight on. I am looking to purchase a hi torque mini start for my 454, seeing as my starter is shot. I've been looking at the DB Electrical SDR0031-L.

Can anyone give me some good reviews on this? I heard someone say the starter drives on their starters are plastic, is that true? It doesn't appear to be by the pictures, maybe the bushing is plastic? I'm not sure what they meant. I've got a tight budget right now and this fits well within it, so I really would like to know if it's worth the buy or should I keep saving for something different? Thanks!
