tS 4.3 has been discontined :( early this year they pulled it from sale.. Entry level atm is 5, and I think they are running a good deal on 6.6 (with plugin packs and training videos.. not sure, check the site to see - www.caligari.com ) I'm thinking tho... with tS 7 round the cornerish.. we may see 4.3 on magazine disks before long.. maybe a coupla months after 7 is released....
