Honestly 6 TE and 3 pots is already a pretty decent amount of buying power.
Obviously I'd like to sell some stuff - I'm currently selling 100/103 Rose for 5 TE and a maxed 4*. I'd also do 7 TE though. I also have a 117/118 Ixtab for sale. Just take a look at my shop if you're interested. That being said, you should look around and try to find the best deal possible.
