Looked into getting a bobbin sander some time ago, started with looking at the Triton, Rutlands, Scheppach, Clarke, Von hause and there are other clones of this machine but ended up getting a small belt sander because it would get more use once I thought about it as I was not doing that much curved work, mainly making the odd template.
I did realise that if / when I do require one then the choice was down to something different, with the Jet being just way to expensive at £800
Jet Jbos-5-m Oscillating Spindle Sander 240v from Westcountry Machinery 4 Wood and really that only leaves two other clones of something similar, Record and Axminster.
There is the Sealey at £516
Sealey Bobbin Sander which is again to expensive for the use it would get and the Itech is cheaper
iTECH MM326 Bobbin Sander with Stand for essentially the same machine.
Axminsters offering is
Axminster Workshop AW140OSS Bobbin Sander - 230V at £360 and the Record which was the one I came closest to buying is now discontinued along with the Charnwood version but available in it's Axminster colors looking like this, or SIP colors as below that.
Whilst Record now sells this latest clone, also available from Rikon if you prefer a square table..
It is interesting to see all the brands stating a machine is now discontinued at the same time showing that there is often more variation in the pricing than the actual machines which all originate from a single source.
