Second hand MacBook for Final Cut Pro advice sought

Hi everyone, 

I do a lot of editing work for a youtube channel with final cut pro. I bought an imac just under a year ago which handles the job very well and I also had to buy an external hard drive to help with storage. My life circumstances have recently changed and I am between 2 houses a lot. I cannot do any editing at the other house and so am considering buying a second hand mac book to bring with me in order to continue working. 

I'm relatively new to Apple and am not at all familiar with mac books. My question therefore is which model would be the best to go for to edit on with a budget of less than 1000 euro. I would need to run photoshop and safari at the same time to create resources for the videos. 

The machine will solely be for editing and I am hoping to have a relatively similar FCP experience on it as on the iMac. If anyone has a different suggestion please feel free to make it, perhaps someone has a better idea!

Any help gratefully received and thanks!
