Hi Fiery and welcome,
Your best bet is to buy a grinder first and enjoy fresh roasted beans in a plunger until you save up some coin to be able to get a machine that will suit your needs. If you get a grinder it will suit your needs later on when you splurge on an espresso machine.
Whilst ever you buy preground coffee you will never get adequate results unfortunately. Sorry no way around that problem. I have no information on teh Saeco so cant help you there but someone else maybe able to give you advice on that soon. If it was good then you could spend the rest of your money on an Iberital Challenge grinder, which is pretty well the entry level espresso grinder.
Hope that gives you some help anyway.
