Maybe when somebody asks specific advice, we should just respond, and not soapbox?
One thing my learning husband appreciated was a pocket voice recorder allowing him to record shiurim, or something nice that somebody was saying.
Also, give more info as to what lines/price you were thinking –
Pen sets, Frame a favorite picture, yummy socks, shabbos raincoat, key chain, mail opener, coffee to go/warmer for the car, scarf, sweater, shabbos alarm clock, basket of his favorite nosh/baked goods, a poem on why you respect him.
Good luck!
