Not sure if you were still after a marker as i saw you said you have just bought an SLG,
however I have:
09 pmr in airforce blue (doesnt have case)-£210
empire reloader B - £30
collectors edition black and gold dye i4's - £60
Dye gun case (holds 2 markers and 4 barell backs/fronts) - £15
Would do all the above for you for £300 posted.
I can get pics up if you are interested
