Transformers Cassette-F22-no-logo (from €46)= same as above but without decepticons logo if you want to add stickers by yourself
Transformers Cassette-F22 cheap version (from € 35)= I used a different sprue (what that keep all pieces together) to contain costs, i've never printed it so it may result in less detail due to difficult polished work or may also come perfectly, you have to try
