picking a martingale

Hoping all my avid shoppers can help me with this I just got a ottb would like to get a running martingale for her but was considering a breastplate with running attachment I want to event her and I'm on a budget so things that are versitale are important can't use running attachment in dressage phase but want breastplate what do you use where can I find a good quality at affordable price

I would suggest going to your local saddlery.. They often have different offers and different prices for different items.
Tell them your situation and the type of horse that you have etc and they will be able to tell you the one that you will likely need.
Alot of places will match prices if you find a cheaper one online so it might be worth while to ask if they will do that too.
Just a thought (:

Dover is having a great closeout sale on the Breastplate I use. It's a VERY nice breastplate!
