If you can't be bothered to service your svd have you thought about the maintenance and upgrades required for a dmr. They all require time and/or more money at some point.
I get it if you've fallen out of love with the svd for a valid reason, but if it's a "I don't want to tech" than I have some bad news for you about maintaining something you want to be precise and reliable.
Also that range on your ssr4 seems short, you should be getting about 50m at 1.1j. are you sure something isn't wrong with it?
