Well my BF and I have decided on $75 limit for each other. No lists... just taking what we have learned from each other over the past few months and see what we can learn from them...
I may be at a disadvantage since he has a mind like a steel trap. LOL
Learned that lesson a couple months back when he surprised me with a crock-pot. May sound like a strange first "real" gift - but we both are trying to eat better and are not great cooks. But we share in cooking, and me with the "flair" for the crock-pot cooking thing - I fix us meals for the week. And it is something we are sharing in.... But he remembered my mentioning a crock-pot as a way for us to save money eating out and eat more healthy.
The disadvantage for me is that I see small techie stuff all the time that I share with with him. Damn divice.com LOL And it seems that remembers it all!!

But in the end I know that I will end up surprised anyhow. Won't say to much on what I have shared - just in case he has signed on to MR.
He is a Mac guy also... we even bought MBA's together the first weekend they were out - him the 11" and me the 13"... And me anything doing with photo gear would be a hit... But he is a bit more subdued in geekdome.
Add to this, his birthday is on 12/19 - think we have agreed to $75 limit for the 19th and the 25th each.... so $150 for that week

But I have been given a free pass as to how I can celebrate his birthday on the 19th - won't over do it though.... we are both not money bags either.
We are looking for it seems for gifts from the heart. Which can make it hard to do at times. In particular for someone like him that loves music, TV, and movies... and me the small tech toys as I mentioned.
I will have to let you all know if I succeeded - I know he will have (the cat is out of the bag on one of his for me) - a Zippo lighter... long story on how that came out of the bag - but I also have the same for him as well...
Two of the gifts so for either of the days are heartfelt in our own ways.. like his giving me a crock-pot. The other two are works in progress. And while a portion of it is based on what I bought - some of it is what I am working on from my heart at the same time.... Still under the $150 limit for both days....
But tempted to ask him if we can amend the rules we have set for each other - found something in the $100 to $150 range that I think is just so perfect.

That would up the anti to close to $200 for his birthday and $75 for Christmas....
