Welcome and don be too put off by all the techno-babble that happens in here, some of it sounds tough, but it isnt really.
For that sort of budget, you could look at something like the EM0480 grinder from sunbeam (the generally accepted bottom "starting point" for espresso grinders) and a Breville Es400 Ikon with either Krups / Breville non pressurised baskets. I use the Ikon at work (still waiting on the unpressurised baskets) and it produces a fairly good coffee but its real strength is the steamer, its a powerful little sucker. You can usually pick these up as factory 2nds (box damaged etc) from outlet stores for circa $ 130 - 150. Add $ 200(ish) for the grinder and you are well under budget. I dont have any experience with the small sunbeam, others here may be able to comment on its abilities.
The pressurised baskets are intended to create "crema" using pretty much any coffee, but with fresh beans and freshly ground coffee, these "crema enhancing" baskets generally detract from the quality of the coffee, not add to it so as part of CS GAP (Coffee Snobs Generally Accepted Practice) we almost always strongly recommend their immediate removal and replacement. It is not a tricky / technical excercise, simply swap one stainless steel filter for another (the same as you would goind from a single to a double filter).
There are likely heaps of recommendations within your budget so take time to read through all the pros and cons of each before dipping your toe in....
