A cheap Chinese DDS based on ADI chips will do function / signal generator to maybe 25 MHz or 50MHz depending on model, but your old one is far more ergonomic. The menu system on the Chinese one I have is dreadful, so I added an old one very like your Isotech IGC2231 Function generator; much easier to use even though it's only up to a fraction of features and frequency.
