I have some opinions, yes. I expect others will be along shortly.
Don't skimp on the grinder! You can make great coffee with fresh beans and a coffee maker costing a few quid, but if your beans aren't ground right, your coffee will always be lacking. I found this fabulous spreadsheet of grinders on the UK Coffee Forums and I generally agree on what they're saying:
http://coffeeforums.co.uk/showthread.php?2956-Grinder-PricesWe bought a Rancilio Rocky, but that was mainly because we make short and long coffee and it's got an easily adjustable grind setting. Otherwise, just for espresso, I was set on the Iberital MC2, which is much cheaper and probably just as good. If you can't afford the cheapest electric burr grinder on this list, buy a manual ceramic burr grinder (I have the Hario slim mill for use at work and although it's not quick, it grinds fine enough for any kind of coffee you could want to make).
If a good grinder has blown the budget then don't buy an espresso machine. At home, we have Tewdric's old Rancilio Silvia and although it's an awesome bit of kit and makes espresso to die for (on the occasions that the coffee gods are smiling on me and everything goes to plan) I drink more coffee from my twenty quid Aeropress than I do from the Silvia.
For the purest and loveliest coffee experience, you don't even need an Aeropress. I also make pourover coffee with a simple paper filter and once you've got your technique right, pourover is delicious.

Seriously - if you're only looking to spend a hundred quid, then get a hundred quid grinder and a few quid's worth of paper filters and a drip cone. You'll make better coffee from the start that way and you'll always have the option of a second hand Gaggia or something at a later date.
