Well, the 300 *is* newer , tho essentially the same machine....I dunno... looked at the fleabay ad , no vice ... but a few bits and consumables, puter and vacuum (good for flat stuff)... if the 2300a comes with a vice it might be worth while. If not , I recon the 300 is a worthwile option ..
Heres prices of accessories for those machines..note vice is relatively expensive... but as I said before , easy to adapt a flat vise tho..
