Valentines day gift

So I wasn't exactly sure which room to post this in, so I hope I don't offend anyone by putting it in here. But currently I am 28 weeks pregnant. I am considering for Valentines day scheduling a 4d (surprise) ultrasound for my husband (and myself)to see the baby. We've only had 1 ultrasound the whole pregnancy. Now the insurance doesn't cover it so it's all out of pocket. It costs $130. Is this ridiculous, stupid, or brilliant? What would your husbands/boyfriends/significant others think?

*I was also going to make a homemade dinner that night as well.
