That's a great choice...I have the save rifle but in a wood stock.
It will shoot ANY HMR ammo into an inch or better on a god day...with it's favorites going sub .500" more often than not, when the wind isn't affecting it.
The trigger is a bit heavy from the factory (about 4.5 lbs) but with some MINOR polishing and a spring swap you'll be at 2.5lbs or a little less with a crips trigger.
I'm a marlin junkie and I truly don't think you can get anything better for the price...I have several marlin rimfires and they are all very reliable. Customer service is easily one of the best/easiest to deal with of ANY company I've ever dealt with.
The rifle you have a link to retails for a little under $200 most places.
IF your budget of $400 is for the rifle alone, you might consider a CZ. You'll get a better trigger, better stock, better fit and finish, and outstanding CZ accuracy...and still be under your goal after tax + fees. The CZ will definitely hold a better resale value as well.
Savage is another choice. Personally, I think they feel a little more "cheap" and the fit and finish isn't quite as great....but they have the accutrigger which is nice (and can be adjusted quite low). Prices are similar with the Marlins.
If you really want my opinion...I'd look for a nice .22mag.
With the new +V ammo out there (30gr Vmax, 30gr TNT, 30gr HP's, etc) they are maintaining a pretty flat trajectory, which packing a bit more punch than the HMR. The "good stuff" is typically about a buck or two cheaper than good HMR, but you also have the option of cheap stuff for plinking at $6-7 a box....something the HMR cannot do.
I've had my HMR for about 2 years, and my .22mag for about 3 months...with the release of this newer .22mag ammo last year, I've retired my HMR from hunting duty. I've found the .22mag to be a better round for the larger of the small game. My groups opened up a bit, as my .22mag is shooting .850-1.00" with ammo it likes, and a little worse with the rest....but that's still plenty accurate for the game I hunt.
