Need help with purchasing a warframe

[(XBOX)Gambrazzio09si]

I just received a 50% off coupon for the market in my daily login bonus and I've heard these are rare. I've been wanting to buy a war frame but I don't want to waste my coupon on a frame I won't like. I've read a little and it looks like Trinity is a good choice but I'm not sure. I have 375 platinum so with the 50% off I can buy a frame up to 750 platinum. I checked and the coupon doesn't seem to work for bundles. Any advice would be greatly appreciated I have less than 2 days to decide

That's actually true. I only mentioned Trinity as an example because OP said he was considering getting her.
