Budget Consideration Reality Check!!
Does the £200 include for mask, pack, pots, squeegey, etc? PMR even 2nd hand might be out of his price range if so. £200 to completely kit yourslef out for pball is about right taking into account a used Ion.
People always seem to forget EVERYTHING you neeed to be able to attend a walk-on or tourney or whatever, and although individually these bits are only £5 each or whatever, it all adds up. A budget is a budget after all.
Ion is a good starter marker. People flame it, but if your budget is limited you'll be able to fire this straight out of the box at 15bps. Job done. May not be the most pimped, efficient or consistent marker, but it aint that bad. I started on one, and I'm sure a lot of others here may confess the same.
You can pimp the outside and modify the innards of the Ion to your hearts content after you bought it, but best bet is to hold back and save the money to upgrade becos you probably will at some point.
EDIT: But saying that, I've got a PMR and it is a nice bit of kit. If you can stretch your budget for one of these, I would heartily recomend one of these over an Ion any day of the week.
