time machine

My buddys wife is switching to pneumatics and said she would sell1me her time machines for about a 100-150 each one is an invader and the other is a flatline she also said she had a really nice machine but i couldnt catch what she said on the phone a darnathis it sounded like. i run all paco rollins machines right now except for my graywash machine which is made out of an old national swinggate i was wondering if anyone had any experience with the machines she is selling. i can only afford one i would like to make whatever i get either a dedicated 7 mag machine so i can use my paco for large mags 9 and up or make myself a nice fast cutback graywash machine. any input would be helpfull Erik
