Pair of ten's reraised preflop level 3

[HelmetCrash]

$20 NL STT. 7 players left, blinds 25/50. I'm UTG with a stack of 800 and raise a pair of tens to 150 preflop. Middle player with bigger stack than me reraises to 250 and everyone folds around to me. My action?

The small amount of the reraise confused me, I felt like I needed to call. I almost would have rather seen my opponent put in a larger raise, then I would have viewed the hand as an all-in preflop problem and it would have been easier to analyze.

Does anybody not like the raise amount? It is 20% of my stack and puts me in a little bit of an awkward position when I am reraised.
