Sorry to hear your news Euge...
Your question is yours and yours alone to answer. However, how much did you like / love your old GR1s? Is there any other make / model that could do the job as well or better? If the answer to the last bit is "no" then get yourself another. If you believe that a Nikon 28Ti (or similar) would do the job better, then maybe it's time to move on.
Incidentally, did you have the camera covered by insurance? Okay, there might be an excess to pay but you might be able to claim the bulk of the cost of replacement back from your policy.
Best wishes in your search for a replacement.
Paul.
