You better save your money buying ADC of 5 $ price and adjust input signal to 1 V p-p.

Why is this? I'm rather new to ADCs and am learning as I go, I figured I would want a single ended input and even if I got a differential I could tie one input to ground and have the same thing as a single ended input.There are well understandable reasons why a 100 MBPS ADC should use differential inputs.
I didn't quite follow that, can you maybe reword it?so biasing one the negative input to Vdd/2 can give e.g. 0..3V input range for a +/- 1.5 V differential input.
Right, but if the absolute maximum is a 4Vp-p then surely I can get a 3Vp-p without harming the device?There is a difference between "Absolute Maximum" which means you won't blow it up and "working" ratings.

Ok so its basically saying you have a 1V window around Vref in which the analog input will be converted.
The analog input can fall outside that window, but it won't be converted.
If the analog input falls outside the range -0.3V to 4.3V it will harm the device.
Some manufacturers specify a maximum input current that can be accepted by the clamp diodes, e.g. +/- 10 mA.If the analog input falls outside the range -0.3V to 4.3V it will harm the device.
