I have the option of getting the following ships, budget of £35, what do I get?

Tie/fo
T-70
Z-95
Tie punisher
Gonzanti
Hounds tooth

Two important questions are "What do you already have?", along with " What is your play style/what do you like to play?"

Knowing those will help us help you better.

It depends on what you have/how you play, of course, but generally speaking, I'd recommend the TIE/fo and the T-70. Then again, if you already have the TFA Core Set, then you'll already have Poe Dameron and the the other T-70 pilots/upgrades might not appeal to you (though integrated astromech is a godsend if you favor the T-65). On the other hand, the TIE/fo contains some fantastic pilots and upgrades (namely Juke and Comms Relay)

If you enjoy Scum (or just want to build it up more), Hound's Tooth is the way to go. It's an incredibly versatile ship with a number of effective loadouts and comes with a great upgrade card selection (Engine Upgrade, K4 Security Droid, Outlaw Tech, Crack Shot, Bossk crew card...)

I have the following:

Core set 1

Core set 2

T-70 x-wing

Rebel Transport

Y-wing x2

HWK-290

K-wing x2

Most Wanted x2

Starviper

Khiraxz x2

TIE/FO x2

TIE/ Interceptor (cards and tokens only)

TIE/ Defender x2 (one full, one ship no cards/tokens)

Imperial Aces

TIE/ Phantom

TIE/ Bomber

Firespray-31

And I can fly just about anything and make it work

In light of that, get whatever you think will be the most fun/whatever you have seen to be fun.

If you don't play much epic I'd skip the Gozanti. If you want more Scum options, grab the YV. Otherwise, grab the two smaller ones.

I agree with Kreen. Get what you like. If you want my opinion, go with the Z-95. You'll get the Munitions Failsafe, Ion Pulse Missile, and another cheap swarm ship to go with you Most Wanted expansion.

Thanks for the feedback guys, I think I shall be buying the hounds tooth and z-95
